According to rainfall characteristics of Yanghe watershed in recent years,the phosphorus export by surface runoff from gentle slope was studied under simulated rainfall and analyzed rainfall data conditions.
根据洋河流域多年的降雨特点,通过对天然降雨资料分析和人工模拟降雨,对该流域缓坡地表径流中磷素输出进行了初步的研究,结果表明:洋河流域缓坡地土壤磷素流失以颗粒态磷为主,不同土地利用方式下洋河流域缓坡地地表径流中不同形态磷含量的大小顺序为:小麦-玉米连作地>高产玉米地>低产玉米地>次生灌木林地;随着降雨强度的增加,径流中颗粒态磷的含量逐渐增加,但Ortho-P的含量却下降;不同植被覆盖度下坡面地表径流中颗粒态磷和TP的含量,随着植被覆盖度增大而减少,但径流中Ortho-P的含量则随着覆盖度的增加而增加。

补充资料：小洋
1.指旧时货币"银角"。"大洋"的对称。银角初发行时﹐原系十进辅币﹐银角十角等于一元。后因铸造过滥﹑成色降低而贬值﹐需十一﹑二角才能兑银元一元。此后﹐贬值的银角就成为小洋。小洋一角一﹑二分合大洋一角。
